MECHANICAL M0,,VEMENT.

SPECIFICATION forming part of Letters Patent No. 290,383, dated December18, 1883.

Application filed October 18, 1883. (No model.)

residing at Oakland, in the county of Goles and State of Illinois, haveinvented certain new and useful Improvements in Mechanical Movement; and.I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements inmechanical movement, its object being to provide a means whereby acontinuous rotary motion will be converted into an intermitting rotarymotion, which may be readily converted again into a reciprocatingmotion, so as to provide a means which may be readily attached andutilized in many different classes of machinery.

For the purpose of illustrating my invention, I have shown the sameapplied to a checkrow corn-planter, which corn-planter, aside from theimproved mechanical movement, possess'es certain novel features, as willbe hereinafter more fully set forth, and are illustrated in theaccompanying drawings, in which- Figure l is a plan View, showing onemanner of applying my invention.. Fig. 2 is a sectional view of myimproved means for con verting the continuous rotary motion into anintermitting reciprocating motion. Fig. 3 is a detailed perspectiveview. Fig. 4 is a plan view of the cord-tightener which is employed whenmy improvement is used upon a checkrow corn-planter, and Fig. 5 is adetail of the edge of the driving-whee A represents the frame of acorn-planter which is provided with seed-boxes B B, which are supportedupon a transverse bar or beam, the center portion of the frame beingprovided with a transverse axle and driving-wheels, as shown, to therear of which is secured the drivers seat in the usual manner? At theend of the beam 0, which supports the seed-boxes are ulle s a a overwhich P y 3 passes a cord or wire, I), which 1s guided by means of thespringpulleys c 0' around the driving-wheel D, which driving-wheel isconcave or wedge-shaped at its rim, as shown at d in Fig. 5, saidconcave or V-shaped groove being provided alternately on opposite sideswith triangular blocks 6, which bite the cord and prevent the same fromslipping in the groove.

The pulleys c c, hereinbefore referred to, are mounted upon springs O,which will take up the slack of the cord and tighten the same in the rimof the wheel. This driving-wheel is also provided with a spring-catch,c, which has a downwardly-extending portion, c. This spring-catch willbind upon the cord and hold the same from slipping.

By means. of a raised portion or block, E, upon the frame thisspring-catch is caused to open at each revolution of the driving-wheel Bas the cord enters the groovedrim of the same, and is opened as the cordpasses from said groove.

By the means hereinbefore described 1t will be seen that a positivemotion is given to the driving-wheel D, though in other styles ofmachinery this wheel may be rotated by other positive means. The shaftF, to which the driving-wheel is rigidly attached, is provided at asuitable point with a wheel or disk,which wheel or disk has cut in itsperiphery two inverted quadrantal arcs or grooves, as indicated by theletters ff, above which is secured or formed upon the wheel a block inthe shape of a pelecoid, the upper portion or part above or to the sideof the grooves, according to the position of the disk G, being curved.By this construction I provide the two grooves f f. Opposite this wheelor disk G, so as to extend at right angles with the axis of the same, isa shaft, H, which is provided at its ends with a yoke, h, which yoke hastwo outwardly-projecting pins, h h.

The end of the shaft H may be provided with an arm, as shown in Fig. 1,or other means for transmitting motion.

In Fig. 1 I have showna crank-shaft,which Y is attached directly to theseed-slides.

The operation of my improved means for converting motion may bedescribed as follows: \Vhen the driving-wheel Dis rotated, it carrieswith it the disk E, and when the portion of the disk provided with thegrooves hereinbefore described comes in contact with the pin h, nearestthe same, said pin enters the groove and passes in said groove below theportion 9, thus causing the shaft h to make one-half of a complete turn.The same pin which enters the groove is then forced upward by the nextarc, and when the pin leaves said are the shaft has made a completerevolution, and the pins upon the yoke will lie adjacent to theperiphery of the wheel.

It is evident that the same movement will be accomplished whether thewheel G is turned either to the right or left, and if it is desired togive the shaft H more than a single intermitting rotary movement withrespect to the disk G, said disk may be provided with two or moregrooves and block similar to that hereinbefore described.

As both the pins upon the yoke h rest upon the surface of the disk G,the shaft will be prevented from rotating except when the pins come incontact with the grooves.

The arm upon the upper portion of the block may serve as the guide toone of the pins while it is passing over the curved portion, the otherpin being within one of the grooves.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device for converting motion, a driving-wheel and shaft providedwith two inverted quadrantal grooves,in combination with a shaftprovided with projecting pins, for the purpose specified.

2. As a means for converting a continuous rotary motion into anintermitting rotary motion,the disk or wheel G, provided with grooves ffand curved projecting portion g, and shaft H,havingpro jectingpinshh,thepartsbeing organized and combined substantially as shown.

3. In combination with the driving-wheel D, provided with a groove andcatch for the purpose of retaining a cord and spring tension devices,the wheel G, with inverted arc-shaped grooves, and shaft H, providedwith projecting pins, said shaft having attached thereto means wherebythe intermitting rotary motion of said shaft will be converted into areciprocating motion, the parts being organized substantially as shown.

In testimony whereof I affix my signatu re in presence of two witnesses.
